1'0 tu whom, it may concern:

Be it known thatI, IsAAc LINCOLN W1LsoN,a citizen of the United States, and a resident of Alberta, in the parish of Bienville and State of Louisiana, have made certain new and useful Improvements in IIot-lVater Distributers for Steam-Generators, of which the following is a specification.

Tater is usually fed into steam boilers or generators at a single place, whereby the adjecent portion of the same is cooled or less heated than others, so that unequal eXpansion results,'with consequent injury to the boiler or generator. I have devised and applied an improvement in that class of attachments whereby the feedwater is divided and distributed and delivered in uniform quantity at a series of places, so that the expansion is equalized and other advantages obtained, as hereinafter stated. The details of construction, arrangement, and operation are as hereinafter described, and illustrated in the accompanying drawings, in which-- Figure 1 is a central longitudinal section of a flue boiler or generator with my improved feed-water divider and distributer applied Fig. 2 is a horizontal section on the line 2 2 of Fig. 3. Fig. 3 is an enlarged central vertical section of the main portion or body of the divider and distributer attached to the boiler and a feed-pipe.

The device, which may be termed the divider]7 A, is a hollow body constructed of metal provided with a series of openings in the bottom and with a central vertical neck a, which is screw-threaded interiorly and exteriorly to adapt it for attachment to the top of boiler B and a feed-pipe O-that is to say, the said neck is screwed into a threaded open ing formed in the top of the boiler, which is preferably provided with areinforce, as shown best in Fig. 3, the upper edge of the neck being preferably flush with the outer side of the boiler. rIhe feed-pipe, which in practice communicates with an injector, doctor, or other means for forcing water, is screwed into the neck, so as to form a water-tight joint. The divider A lies as close to the inner side of the top of the boiler as practicable. A series of distributing-pipes D are attached to the bottom of the divider where the holes are located, as aforesaid, and the same extend horizontally in the steam-space, their outer ends being provided with pendent pipes that eX- tend down below the third line of flues b. It

will be noted that the pendent portions of the distributing pipes D are located equidistantly from each other and from the ends of the boiler, so that the feed-water will be distributed therefrom at equidistant points. The divider or primary waterreceptacle A may be quite small, but it should have a greater capacity than the feed-pipe C, and the holes in the bottom where the distributing-pipes D are attached should be comparatively large, so that water will flow slowly from the divider through the said pipes. The ends of the pipes D being flush with the inner surface of the bottom of receptacle A and the latter being horizontal it is apparent that even a small quantity of water entering the divider will be equally distributed to the said pipes, and thereby to the several points of discharge.

The feed-water is heated to a considerable degree before reaching the several points of discharge. It will be seen that by my improved apparatus or attachment feed-Water is distributed in equal volume at several different points in the boiler, so that it has no effect in producing an unequal expansion of the latter and becomes more quickly mingled with the body of water in the boiler, and thus also more quickly heated.

It will be understood that the divider or receptacle A may be made in different sizes to suit different-sized feeders and that the divider may be connected in different ways with the feed-pipe proper. If the injector or other feeder will not lift the water to the height required, it may be placed on a level with the top of the boiler.

My improved hot-water distributer aids in maintaining a more uniform steam-pressure, since steam is not reduced in quantity to the same degree as when water is introduced in the ordinary manner; Oontraction and eX- pansion of the boiler are also lessened, since no cold water comes in contact with the boiler, but is discharged in comparatively small streams at different points into the great body of heated water.

Vhat I claim is- The combination, with a steam-generator having a series of horizontal flues, of a waterdistributer comprising a tubular receptacle which is attached to the top portion of the boiler and adapted for connection with a feedpipe, and a series of distributing-pipes eX- tending horizontally from the receptacle and IOO having pendent portions that extend below the third line of fines, the said receptacle and the horizontal portions of the distributing pipesbeing thus arranged in the stearn=space is normally supplied, substantially as described.
